RICHARD R. SGOGGAN,

OF JEFFERSONVILLE, INDIANA, ASSIGNOR T0 KENTUCKY SWITCH 8a SIGNAL 00., INC., OF ST. MATTHEWS, KENTUCKY, A CORPORATION- OF KENTUCKY.

Original application filed August 4, 1920, Serial To all whom it may concern Be it known that I, RICHARD H. SooeoAN, a citizen of the United States, residing at Jeffersonville, in the county of Clark and State of Indiana, have invented new and useful Improvements in Trolleyire ,Con-

tactors, of which the following is a specification.

This invention relates to trolley wire contractors or trolley pans used in connection with electrically controlled railway switches and is especially adapted for use with the type of electrically controlled railway switch described in my copending application Serial No. 401,152 filed Aug. 4, 1920, of which this application is a division.

The primary object of this invention is to provide a trolley wire contactor of greatly reduced weight, size, length and number of parts, and one which reduces arcing to a minimum and requires no deflection of the trolley wire, but eliminates the arc barrier and the necessity of trolley contact runways of unequal length.

Other objects of the invention including novel features of construction and mode of operation will become apparent on reference to the following specification which describes the invention in connection with the accompanying drawings.

In the drawings 2- Figure 1 is a side elevation partly in section of the novel construction of trolley wire contactor or trolley pan and the means for supporting the same.

Fig. 2 is an end view of the contactor shown in Fig. 1, the trolley wire being shown in section on the line 22 of Fig. 1.

Fig. 3 is a sectional view on the line 3--3 of Fig 1.

Fig.4 is a sectional of Fig. 1.

Numerals 10 and 10 represent end brackets having a channel for receiving the trolley wire 11 and also a V-shaped section, the sides of which, designated as 12 in Fig. 3 receive the sides of a rectangular insulating block 13. The numerals 14 and 14 designate angle strips of metal which are bolted to the block 13 by means of the bolts 15, 15 which penetrate through opposite sides of the block. The angles 14, 14 thus form a beveled channel or runways for the trolley wheel 16 and are insulated from the trolley wire and from each other and when used view on the line 4-4 Specification of. Letters Patent.

Iatented Nov. 1, 1921.

with the switch throwing mechanism described in my above mentioned application these runways are preferably of equal length but in the general application of this invention they may be of equal or unequal length. The numerals 17 17 designate trolley wire cars which have a curved or grooved lower edge adapted to hold the trolley wire firmly down in the channel of the brackets 10, 10. The members 17, 17 are T-shaped at one end (see Fig. 2) the extending arms of the T-section being secured to the brackets 10, 10 by means of fastening devices 18, 18. A casting 19 is bolted to the upper face of the block 13 preferably by the extended bolt 15 and this casting is provided with a boss 20 adapted to receive the threaded stem of a standard trolley wire insulated hanger 21 which forms a support for the whole contactor.

No. 401,152. Divided and this application filed. J'an- I nary 7, 1921. Serial No. 435,667.

The trolley wheel after passing bracket 10, spans the runways 14, 14 and thus con nects them electrically to energize the switch throwing mechanism.

Having described claim as new and ters Patent, is

1. In a trolley wire contactor, the combination of a supporting block of rectangular form, end brackets secured to the block having a V-shaped channel formed therein for receiving the block and the trolley wire and means secured to said end brackets for clamping the trolley wire firmly in said channel.

2. A trolley wire contactor or trolley pan including a supporting block placed cornerwise, runways for the trolley wheel angularly disposed on adjacent faces of said block, and means for supporting the trolley wire without deflection below said block between said runways and out of contact with the trolley wheel.

3. A trolley wire contactor or comprising a rectangular block, end brackets secured thereto having V-shaped channels formed therein, members attached to said end brackets having grooves formed therein adapted in conjunction with said channels to embrace the trolley wire and hold it firmly in position, runways secured to said block between which the trolley wire extends and an insulated hanger mounted on said block for supporting the same.

4. A trolley wire contactor or trolley pan comprising a rectangular block of insulating trolley pan material having a diagonal thereof disposed substantially vertical, metallic runways angularly disposed from opposite slanting sides of said block adapted to contact with the flanges of a trolley Wheel, and means for supporting the trolley wire in its normal path between said runways and below said block, the trolley Wheel being depressed out of engagement with the trolley wire by said runways.

5. In a trolley wire contactor or trolley pan, the combination of a block having run- 'wa s an ularl dis osed thereon a su orty a Y a ing bracket secured to the upper portion of the block and common fastening devices for one of said runways and said bracket.

6. A trolley wire contactor comprising a supporting block having angularly disposed faces forming a dihedral angle, runways for the trolley wheel consisting of angles having arms secured to said faces respectively and their other arms projecting ways for the trolley wheel, and

outwardly therefrom, a corner of said block formed by the dihedral angle extending between said projecting arms, and means for supporting said trolley Wire between said runways and out of contact with the trolley wheel. v

7. A trolley wire contactor comprising a supporting block having angularly disposed faces forming a dihedral angle, angle runfastening devices passing through the supporting block from both of said angularly disposed faces and through the arms of said angles which are not used as a running surface for the trolley wheel.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
